[L'ennemi.]

I'haven't seen the show, but based on your description it probably sucked. I hate when they interview family members like that it is so stupid.
That being said the show seems to be fair to conspiracy theorist for two reasons. He let these people gives their accounts of the event, and they try to show why their theory it stupid, which might give you the illusion that this arguments are listening to.
the real question is not fact or fiction? but Where do they find these people? And how come our school system sucks so much that a lot of people believe that crap?
